項目簡介：

????????開發語言：C++

? ? ? ? 開發軟件：Qt Creator 4.6.2?

? ? ? ? 實現功能：目前所能實現的功能比較單一，只支持人人對戰，也就是兩個人在一臺電腦上實現對戰。

項目思路：

????????1、繪制棋盤

????????2、繪制棋子

????????3、放置棋子于棋盤之上

????????4、倒計時

????????5、象棋輪流下

????????6、制定象棋的具體規則

項目主要組成：

1、總的文件（其中chessmovelaw文件是自定義文件，res是資源文件，包括棋盤、棋子、應用程序logo等圖片）

?2、主要代碼
